摘要

Recently, optical fiber sensors have been increasingly applied to monitor variousengineering and civil structural components. These fiber optic smart structuresallow engineers to add nervous systems to their designs, giving structurescapabilities that would be very difficult to achieve by other means, includingcontinuous assessment of damage processes. Several studies associated withcrack monitoring using optical fiber sensors have been reported. In thisstudy, we used recently developed transmission-type extrinsic FabryPerotinterferometric (TEFPI) optical fiber sensors for the monitoring of fatigue crackgrowth behavior of cracked thick aluminum plate repaired with a bondedcomposite patch. The TEFPI optical fiber sensor has both the advantages ofreflection-type EFPI optical fiber sensors and a simpler and more effectivefunction to distinguish strain direction than do reflection-type EFPI opticalfiber sensors. The objective of this study is to evaluate the potentiality ofthe application of TEFPI optical fiber sensors to the monitoring of thefatigue crack growth behavior of composite patch repaired structures.The sensing principle and the sensor construction of the TEFPI opticalfiber sensor are presented. The experimental results from fatigue testsof center cracked tension aluminum specimens repaired with a bondedcomposite patch are presented and discussed. TEFPI optical fiber sensors areembedded and surface bonded to the composite patch at several locations. Theexperimental results show that it is possible to monitor the fatigue crack growthbehavior of composite patch repaired structures using TEFPI optical fibersensors.
